Real Time Monitoring
TMU rapidly monitor every parameter’s movement, With web-based view, allowing you to watch the transformer anytime and anywhere seamlessly.
Failure Identification
If any monitored parameter exceeds the limit, TMU will automatically classify it into a fault classification. This will make it easier for technicians to determine the type of disturbance and handle it quickly and precisely
Brief Analysis
With Analysis feature allows TMU to present deeper data for analysis so that it can be used to determine transformer performance, Transformer disturbances, predict the tendency of disturbances and potential improvements that can be implemented.

Gas Fault Detect
With Analysis feature allows TMU to present deeper data for analysis so that it can be used to determine transformer performance, Transformer disturbances, predict the tendency of disturbances and potential improvements that can be implemented.
WTI
Without spending enormous money for ultra-expensive sensors. TMU already equipped with each phase Winding Temperature Indicator to guarantee that transformer is running normally.
K-Rated & De-Rating
TMU accurately measure Harmonic Distortion, then precisely identify the K-Rated of transformer which leads to de-rating recommendation if you are using too much load while using lot of non-linear load.
